To all whom it may concm: v

Be it known that we, LEMUE'L A. CARTER, J AMES C. J oNEs, and J AMES C. Srorrs, citizens of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in Heating or Cooling Apparatus; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates toheating or cooling apparatus of the tubular boiler type, and has for its purpose to provide an apparatus of that character wherein the liquid to be treated is more effectively subjected to the heating or cooling inluences of the medium employed, and for a relatively greater periodduring its passage through the apparatus than has been heretofore proosed.

The invention has for its further object to present a construction wherein the series of tubes for the passing liquid are more rigidly secured within the boiler or shell thanl are the tubes of other apparatus of this general character thereby prolonging the life of the.

.tubes and increasing the efficiency of the apparatus as a whole.

With these and other ObjectsA in view the invention. consists in the arrangement. and combination of parts hereinafter claimed, and while the invention is not restricted to the exact details shown and described, still for the purpose of disclosure reference is had to the accompanying drawings, in which like reference characters designate the same parts in the several views, and in which Figure 1 is a side elevation of the apparatus with the cylinder in section. Fig. 2 is a top plan' view thereof with the cover plate removed, and showing the design of shell employed. Fig. 3 is a central vertical sectional view taken on the line 3.-3 of Fig.

2. Fig. 4 is a transverse sectional view' taken on the linefl--ll of Fig. 3, and looking in the direction of the arrows. Fig. 5 is a central vertical section of the apparatus illustrating the direction of flow of the fluid, and Fig. 6 is a detail, partly in elevation and section, showing the means for conducting the iluid from one series of chambers to another.

Referring to the construction in further shell 1 which is of substantially deslgn in cross section, and which at op osite ends is constructed with heads 2 and "l i; that have each an annular extended portion ll to which the end or closure plates 5 are secured, and providingannular shoulders.

1 and consisting staves 6, is'secured to said shell through the detail wherein like reference characters iny dicate corresponding parts in the different views shown, the apparatus consists of a r hexagonal A cylinder or outer casing for the shell 1, 'of a plurality of wooden medium of a plurality of hoops or bands 7 which hold the staves assembled and against the heads of the shell in the manner illustrated in Fig. 3.

The shell 1 is provided with a plurality of radially disposed ribs or llanges 8 and 9 that are located on and lengthwise of said shell at the point of ymeeting of the sides thereof. Said flanges meet' flush against the inner surface of the cylinder and provide therewith a plurality of closed compartments which will be presently referred to. The ribs 9 are arranged alternately with the ribs 8'and are disposed in pairs and in relative angular relation. Each pair of ribs 9 provides, with the inner face of the cylinder,

anchannel or water passageway 10 substan-` tially V-shaped in cross section, and whose purpose is to conduct the circulating fluid y from one series of chambers to the next ad] acent series (see Fig. 6) as will be presently described. Between each pair of radial ribs 8 .and 9 there is provided a plurality of longitudinal or segmental ribs l11 which with saidradial ribs divide the compartments into a plurality of liquid chambers 12. Said chambers 12 are arranged in groups or series, of which there is one series-tofeaoh side of the hexagonal shell and the ,chambers of the dilferent series are arranv ed in staggered relation. The individual chambers 12 of each series are isolated from each other, and the lowermost chamber of each series communicates with the uppermost chamber of the next adjacentseries to the right by means of the passageway or channel 10 as above pointed out.

Located within the shell 1 is a plurality of pipes or tubes 13 arranged in groups or parallel series as illustrated and secured within the sides of the shell in any appropriate manner. The tubes of each horizontal group are secured within opposite parallel sides ot the shell il, by which arrangement the ends of all the tubes have uniform and square bearings as distinct from non-uniform and angular bearings as is the case with securing the tubes in a cylindrical shell in apparatus of this character. ythe tubes are arranged to bring each chamber l2 ot one series into communication with two chambers of the (iliametrically opposite series so that tsce Figs il and a How of liquid will be from the inlet pipe linto one chamber, through a group of pipes into a lower chamber on the opposite side ot the shell; from this chamber through another set of tubes into a lower chamber of' the opposite series and so on across all of the tubes in the same vertical series and through all of the tubes on opposite sides of the shell. At the end of this course, z'. c. when the fluid enters the lowest or bottom chamber of one side it passes into the uppermost chamber of the next adjacent side to the right. From this point the iiuid takes precisely that course just described, and in like manner it tiows through all of the chambers and tin-ally passes ott through the outlet pipe l5.

W'hilc in the drawings the shell is shown with its cross-section in the form of a hexagon, which is the preferred construction, it will be obvious that its form may be in the shape of any polygon having oppositely disposed parallel laces. The advantage of this polygonal arrangement is that the tubes may be made of equal length, whereas with tubes crossing a. cylindrical shell, the lengths would vary.

It is obvious that those skilled in the art may vary the details of construction and arrangement ot' parts without' departing from the spirit ot our invention, and therefore we do not wish to be limited to such features except as may be required by the claims.

that we claim is l. In a water heating or cooling apparatus, the combination of a cylinder; a shell located within said cylinder and spaced therefrom; ribs on said shell providing series ot chambers, the chambers of each series being disposed in straight alinement and arranged in staggered. relation with respect to the chamber of the next adjacent series; tubes passing through the shell and connecting opposite sides of said chambers; and means for conveying liquid to and causing the same to traverse said chamber and tubes and drawing oit said liquid, substantially as described.
